ABSTRACT:
Apparatus for connecting motors in tandem and particularly in vertical alignment includes a coupling for connecting the lower end of the shaft of the upper motor to the upper end of the shaft of the lower motor. A tubular member surrounds the coupling with its upper end extending into the outer housing of the upper motor and its lower end threaded into the outer housing of the lower motor. A lock ring surrounds the tubular member and has a keyed connection with the outer housing of the lower motor. The upper end of the lock ring and the lower end of the outer housing preferably have ten equally spaced keyways therein. A key extends into a pair of matching keyways of the lock ring and upper outer housing and screws hold the keys in place by passing through aligned holes in the lock ring and upper outer housing into threaded holes in the tubular member.
